AHMEDABAD – Adani Cement, together with group associate PSP Infra, has completed the world’s largest raft foundation for a religious structure at the Umiya Dham temple near Ahmedabad, the company said on Thursday.

The 54-hour continuous operation involved the pouring of 24,100 cubic metres of ECOMaxX M45 grade low-carbon concrete, a proprietary sustainable mix developed by the company. Adani said the process cut carbon emissions by 60%.

The foundation, measuring 450 ft by 400 ft and 8 ft thick, will support 1,551 pillars for the 504-foot Jagat Janani Maa Umiya Temple, billed as the world’s tallest temple once completed.

The pour was carried out using 26 ready-mix concrete plants, more than 285 transit mixers, 3,600 tonnes of cement and a workforce of about 600. The operation was planned to avoid cold joints and maintain temperature control, Adani said.

“Umiya Dham is set to become a landmark, representing an investment of about 20 billion rupees ($240 million),” said Vinod Bahety, CEO of Adani’s cement business. “This project embodies the scale, speed and sustainability that define Adani Cement.”

R.P. Patel, president of the Vishv Umiya Foundation, which is overseeing the project, said the foundation was a “proud moment for India’s cultural and engineering heritage.”

The casting was witnessed by more than 1,000 people on site and 10,000 online, according to Adani.

The company said its ECOMaxX mix used 66% supplementary cementitious material and a proprietary formulation that kept concrete placement temperatures below 28°C to minimise thermal stress. Sensors embedded in the structure continue to monitor durability.

Adani Cement, part of billionaire Gautam Adani’s conglomerate, has been involved in several large-scale projects, including Mumbai’s World One Tower and the Chenab Railway Bridge in Jammu and Kashmir.
